T0 ALL WHOM IT; MAY CON CERN:

Be it known that I, WILLIAM F. SHAW, of Boston, countyof Su'olk, andCommonwealthbf Massachusetts, have invented a new and useful ImprovedDome-Shade;and I hereby declare thelfollowiugto be a full, clear, andexact description thereof, which will enable others to inake and use myinvention, reference being had to the accompauyingd-rawi'ngs, formingpart of thisspecification, iu which is `exhibited a side elevation ofiuyimproved shade,.\vith its holder; also, a bottom or top -edge view ofthe holder.

A. shows the side elevation,- B the top or bottom edge view'ot' theholder@` Similar Vforms of shades have before this been manufactured ofbrass and other materials, the peculiar character'- of them-aterialemployed rendering the manner of manufacture feasible. The domeorsemi-spheridal foim is imparted by hammering;`

i or being spun up in a lathe.A But this is, in comparison with myprocessof manufacture, expensive, involvf ing a. considerably highercost in the completed article. i i

My improved shade is made, in the first place, from one piece oft'instruck up in ,a press.4 `The material employed and mode ofmanufacture greatly lessen the cost. i -Morcoverg tin is a metal `thatcannot `be used for this purpose, and be manufactured into the formshown in the drawingsror similar forms,iby being spuuup, inasmuch asfrom its nature it will not admit oi' such a method to s'uicient depthto manufacture an article i like this. B is the holder or ring thatembraces the burner or chimney to-sustanthe shade. It is corrugated, andmay be made either of flat metal, as illustrated in the drawing, or ofwire. Whenlthus made of dat metal, p i and corrugated, it easily adjustsitself to varying sizes of 'burners or chimneys, and maintains the shadein a secure and upright position, sufficient to prevent its inclinationor striking against chimneys, xtc., overjwhicli it may be placed. 1 2 3show the rods or outrnnncrs uniting the adjustable holder to the dome,as`common.

What I claim as my' invention, and desire to secure by Letters Patent,isi 1. The corrugated adjustable holder B, as and for the purposesspecified.

2. The improveddome-shade, when manufactured of the material and in themanner herein set forth and for the specified purposes.
